Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. As with many other companies STINAG Stuttgart Invest AG (FRA:STG) makes use of debt. But the more important question is: how much risk is that debt creating?
Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. Of course, debt can be an important tool in businesses, particularly capital heavy businesses. When we examine debt levels, we first consider both cash and debt levels, together.
The chart below, which you can click on for greater detail, shows that STINAG Stuttgart Invest had €157.7m in debt in June 2025; about the same as the year before. On the flip side, it has €17.0m in cash leading to net debt of about €140.7m.
According to the last reported balance sheet, STINAG Stuttgart Invest had liabilities of €1.19m due within 12 months, and liabilities of €173.2m due beyond 12 months. Offsetting this, it had €17.0m in cash and €4.97m in receivables that were due within 12 months. So its liabilities total €152.3m more than the combination of its cash and short-term receivables.
This is a mountain of leverage relative to its market capitalization of €198.0m. This suggests shareholders would be heavily diluted if the company needed to shore up its balance sheet in a hurry.
See our latest analysis for STINAG Stuttgart Invest
We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (interest cover). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.
With a net debt to EBITDA ratio of 8.4, it's fair to say STINAG Stuttgart Invest does have a significant amount of debt. But the good news is that it boasts fairly comforting interest cover of 2.9 times, suggesting it can responsibly service its obligations. More concerning, STINAG Stuttgart Invest saw its EBIT drop by 3.2% in the last twelve months. If it keeps going like that paying off its debt will be like running on a treadmill -- a lot of effort for not much advancement. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if STINAG Stuttgart Invest can strengthen its balance sheet over time. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.
But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Considering the last three years, STINAG Stuttgart Invest actually recorded a cash outflow, overall. Debt is far more risky for companies with unreliable free cash flow, so shareholders should be hoping that the past expenditure will produce free cash flow in the future.
On the face of it, STINAG Stuttgart Invest's conversion of EBIT to free cash flow left us tentative about the stock, and its net debt to EBITDA was no more enticing than the one empty restaurant on the busiest night of the year. Having said that, its ability to grow its EBIT isn't such a worry. Overall, it seems to us that STINAG Stuttgart Invest's balance sheet is really quite a risk to the business. For this reason we're pretty cautious about the stock, and we think shareholders should keep a close eye on its liquidity. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it.
